Answer:
a) y = 4x - 2b) y = 3x + 2c) y = 2x - 6Step-by-step explanation:
a)
The slope as per two ordered pairs (-2, -10), (0, -2)
m = (-2 - (-10))/(0 - (-2)) = 8/2 = 4The y-intercept is -2
The equation for this function:
y = 4x - 2b)
The slope is
m = 3The line passes through (1, 5)
The line is:
y - 5 = 3( x - 1) in point-slope formy = 3x +2 in slope-intercept formc)
The slope as per points on the graph (3, 0), (4, 2)
m = (2 - 0)/(4 - 3) = 2The line in point slope form using point (3, 0):
y = 2(x - 3)The line in slope-intercept form:
y = 2x - 6a) substitute m = 4 and c = - 2 into the slope intercept equation, thus, the equation of the line is y = 4x - 2
The answer is y = 4x - 2
b) Let's begin by listing out the given information:
The line has a slope of 3
The equation of the line becomes:
[tex]y = mx + b \\ m = 3 \\ y = 3x + b[/tex]
The line passes through point (1, 5).
We will obtain the equation using the point-slope formula, we have:
[tex]y - y1 = m(x - x1) \\ (x1 \: y1) = (1 \: 5) \\ y - 5 = 3(x - 1) \\ y - 5 = 3x - 3 \\ y = 3x - 3 + 5 \\ y = 3x + 2[/tex]
Therefore, the equation of the straight line is y = 3x + 2
c) we use that point and the slope to replace in the expression:
[tex]y - y1 = m(x - x1)[/tex]
That is:
[tex]y - 0 = 2(x - 3) \: \: y = 2x - 6[/tex]
y = 2x - 6 is the answer
A biologist is studying a bacteria population that initially contains 10^3 bacteria. In the lab, the population doubles every week. The expression 10^3×2^w models the population of the bacteria after w weeks. How many bacteria will be present in 3 weeks? CK12
Answer: 8000
Step-by-step explanation:
From the question, we are informed that the expression 10³ × 2^w models the population of the bacteria after w weeks.
The number of bacteria that will be present in 3 weeks will then be:
= 10³ × 2^w
= 10³ × 2³
= 1000 × 8
= 8000 bacterias

Hope this helps :>From Cambridge please give brainliestHow do I solve equations with a variable to the power of something (give steps please)
Like these.
[tex]2x^2+5x=0[/tex]
Answer:
Step-by-step explanation:
Factoring will reveal the solution. So we divide the equation by the greatest common factor of the terms and use that factor as the coefficient. In this case the greatest common factor is just x.
2x^2+5x
x(2x+5) so the equation will equal zero when either of those expressions is zero because zero times anything is zero. x=0 and x=-5/2
Answer:
[tex]x = 0, -\frac{5}{2}[/tex]
Step-by-step explanation:
First move all terms to one side of the equation to set them equal to 0
That is already done in your problem
The try to factor, if possible. In your case, factor out x
x(2x + 5) = 0 Now, use the property that says if AB = 0, then A = 0 or B = 0 or both A and B equal 0
So, x = 0 or 2x + 5 = 0
2x = -5
x = [tex]-\frac{5}{2}[/tex]
Always check your results in the original equation to see if they work
[tex]2(0^{2} + 5(0) = 0 + 0 = 0\\[/tex]
and [tex]2(-\frac{5}{2} )^{2} + 5(-\frac{5}{2} )\\ = 2(\frac{25}{4} ) - \frac{25}{2} \\ = \frac{25}{2} - \frac{25}{2} = 0[/tex]
Both results make the equation true, so [tex]x = 0, -\frac{5}{2}[/tex]
find the value of x please help
using angle sum property
we get
110+35+(x+12)=180
(x+12)=180-145
(x+12)= 35
x= 35-12
x= 23
Answer:
Angles in a triangle are sum up to 180 degrees.
35 + 110 + (x+12)=180
145+x+12=180
157+x=180
x=180-157
x=23 degrees

Answer: C
[tex](15)^{2} =a^{2} +(9)^{2} \\\\225=a^{2} +81\\\\a^{2} =225-81\\\\a^{2} =144\\\\a=\sqrt{144} \\\\ answer : a=12[/tex]
Step-by-step explanation:
hope it help have a nice day
Answer:
a = 12
Step-by-step explanation:
Based on the Pythagoras theorem...
[tex]c^{2} = a^{2} + b^{2}[/tex]
(where c is the hypotenuse, and a and b are the legs of the right angle triangle)
Therefore we can rewrite it as...
[tex]c^{2} = a^{2} + b^{2}[/tex]
[tex]15^{2} = a^{2} + 9^{2}[/tex]
[tex]225 = a^{2} + 81[/tex]
[tex]a^{2} = 225 - 81\\a^{2} = 144\\a=\sqrt{144} \\a = 12[/tex]
I need help with this multiple choice question.
Given the diagram below, which statement is true?
Show your work.
Answer:
D. XY > WY
Step-by-step explanation:
The angles in a triangle add to equal 180°, so subtract 180°-55°-58° and 180°-64°-61° for the missing values of ∠WYX and ∠YXZ, respectively: ∠WYX = 67°, ∠YXZ = 55°.
The longest side of a triangle is opposite the largest angle, and the shortest side of a triangle is opposite the smallest angle:
In the triangle on the left, the shortest side must be XY because it is opposite the smallest angle, ∠W; the longest side is WX, which is opposite the largest angle, ∠WYX (67°).In the triangle on the right, the shortest side is YZ, opposite the smallest angle, ∠YXZ (55°); the longest side is XZ, opposite the largest angle, ∠XYZ (64°)ABC is translated 2 units right and 1 unit down.

Answer:
The equation is:
y = -15*x + 1200
and:
a = 120
b = 70
c = -1500
Step-by-step explanation:
This seems to be a linear relationship.
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Here we know that our line passes through the points (60, 300) and (20, 900)
Then the slope of this line is:
a = (900 - 300)/(20 - 60) = 600/(-40) = -15
Then this line is something like:
y = -15*x + b
To find the value of b, we know that this line passes through the point (60, 300) then when x = 60, we have y = 300.
Replacing these values in the above equation we get:
300 = -15*60 + b
300 + 15*60 = b = 1200
Then:
y = -15*x + 1200.
Now that we have this equation, we can complete the table.
a is the value for y, when x = 72
Then we can replace x by 72 in the above equation:
a = -15*72 + 1200 = 120
a = 120
b is the value of x when y = 150, then we need to replace y by 150
150 = -15*b + 1200
150 - 1200 = -15*b
(150 - 1200)/-15 = b = 70
then:
b = 70
c is the value of y when x = 180, then we need to replace x by 180.
c = -15*180 + 1200
c = -1500
find the value of x .
Answer:
49.79
Step-by-step explanation:
Using SOH CAH TOA;
Le the height be h
Tan 70 = h/16
h = 16tan70
Get the value of x
Opposite = 16tan70
hypotenuse = x
sin 62 = 16tan70/x
x = 16sin70/sin62
x = 16(2.7475)/0.8829
x = 43.96/0.8829
x = 49.79
Hence the value of x is 49.79
